Migration of Foreign Bodies from the Upper Digestive Tract: A Case Series
Abstract:
Fish bones are considered to be sharp foreign bodies and can penetrate the digestive tract. These penetrations are rarely observed but can pose serious complications when they happen. We present two-case studies where ingested fish bones were found to have migrated from the upper digestive tract to the retropharyngeal area. Initial examinations and endoscopies of the neck returned negative results. The subsequent computed tomography scans documented the locations of the fish bones. Surgical neck explorations were performed via a lateral neck incision and the fish bones were successfully removed from the patients.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
